Abstract
In order to study the influence of moisture content change and rainfall infiltration on the stability of bedding slopes with soft rock interlayer, a highway slope in Guangxi was taken as an example. The moisture content change of bedding slope and the influence law of rainfall infiltration condition on slope safety factor was analyzed by considering the change characteristics of strength parameters of soft rock interlayer with moisture content. The results show that there is a negative exponential relationship between the strength parameters of soft rock interlayer and the moisture content, and there is a critical moisture content. When the moisture content of the soft rock interlayer exceeds the critical value, the most dangerous sliding surface will change from the slope toe circle to sliding along the soft interlayer. Under the condition of rainfall infiltration, the increase in sliding force caused by rainfall in the early stage has no obvious effect on the slope safety factor. As the rainfall continues, the areas in the shallow surface of the slope affected by rainfall infiltration are more prone to instability.
